Removed boolean and list of enabled worlds on every drop, sorry! :( I've learned to mark my debug messages so that they are easy to find and remove before releasing a plugin/update publicly.
v1.1.0
Added per-world support, please set enabled worlds in config!
Removed old, commented-out code from DropListener class (Does not affect servers regardless).
v1.0.4
Fixed how silk touch reacts to banners.
v1.0.3
Added silk touch support.
v1.0.2
Fixed wrong permission node in a method.
Fixed ignoring protections such as WorldGuard.
v1.0.1
Removed unnecessary boolean and check.
v1.0.0
First official release! Yay!
Tested on 1.8.8, should work on lower versions, too.
v1.1.0
Possibility of message like "Item entity <random number> has no item?!" to show in console log when an item is broken. If found, please report it to me and I'll fix it.
